Title: Sintering method for molded body of iron based powder
Inventor: SAKURADA KAZUO
IPC: B22F3/10
Filed: 1980-09-17
Abstract: PURPOSE: To prevent decarbonization even when sintering in a reducing atmosphere of a relatively high dew point and prevent oxidation even when sintering an alloy steel containing Mn, Cr or the like by a method wherein graphite coated on a molded body of an iron based powder and water content in an atmosphere are brought into a water gas reaction.  
     CONSTITUTION: Graphite is coated on the molded body of the iron based powder. The molded body is then sintered at 1,000W1,250°C, while the graphite coated on the molded body and the water content in the reducing atmosphere are brought into the water gas reaction. In this case, the prevention of decarbonization is achieved by both the effect of the preferential reaction of the graphite with the water content in the atmosphere, which effect prevents the escape of combined carbon, and the carbonizing effect of the CO gas formed by the reaction. In addition, in the case of sintering a molded body of an alloy steel powder containing Mn, Cr or the like, it is considered that the preferential reaction of graphite and water content produces an effect of apparently reducing the dew point of the atmosphere in contact with the surface of the sintered body, thereby preventing the oxidation of Mn, Cr or the like. The lower limit of sintering temperature is determined in view of the hardness and strength of the part to be produced from the Fe-C based powder by powder metallurgy, while the upper limit of sintering temperature is determined in view of the structure of the furnace used.

Title: Negatively electrostatically charged cyan toner for color electrophotography
Inventor: KUSUMOTO TORU
IPC: G03G9/09
Filed: 1990-05-18
Abstract: PURPOSE:To obtain an excellent electrostatically charging characteristic, aging degradation resistance and moisture resistance by using a phtalocyanine series blue organic pigment whose surface is covered with a negatively electrostatically charged hydrophobic silica as a coloring agent. CONSTITUTION:The surface of the phtalocyanine series blue organic pigment is covered with the negatively electrostatically charged hydrophobic silica. By covering the surface of the pigment with the negatively electrostatically charged hydrophobic silica, a positive charge for which the pigment itself has, is neutralized or the pigment is electrostatically charged at a negative side. Then the polarity of the toner is coincided with that of the pigment and the occurrence of the opposite electrostatically charged toner is prevented. Also since the silica has a hydrophobic property, the improved moisture resistance is provided in a high humidity condition. Thus the negatively electrostatically charged toner with the improved electrostatically charging characteristic, aging degradation resistance and moisture resistance is obtained.
